Check Digit Verification of cas no

The CAS Registry Mumber 204985-91-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,9,8 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 204985-91:
(8*2)+(7*0)+(6*4)+(5*9)+(4*8)+(3*5)+(2*9)+(1*1)=151
151 % 10 = 1
So 204985-91-1 is a valid CAS Registry Number.

Tetrakis(Trimethylsilyl) ethenylidenebisphosphonate: A mild and useful reagent for the synthesis of substituted 2-aminoethylidene-1,1-bisphosphonic acids

Shevchuk, Michael V.,Romanenko, Vadim D.,Kukhar, Valery P.

, p. 799 - 801 (2011)

Tetrakis(trimethylsilyl) ethenylidenebisphosphonate is proposed as a substrate in the preparations of N-substituted 2-aminoethylidene-1,1- bisphosphonic acids. The method provides an extremely mild protocol for the synthesis of these compounds and is compatible with a wide range of functional groups. Copyright Taylor & Francis Group, LLC.
